Apache CloudStack is fully open-source and built on open standards. Unlike proprietary stacks, you retain full control of your infrastructure, roadmap, and costs without dependency on a single vendor or licensing model.

CloudStack with KVM dramatically reduces licensing and support costs compared to VMware environments. Providers achieve significant savings by moving to open-source infrastructure without sacrificing enterprise capabilities.

CloudStack was designed from the ground up for MSPs, CSPs, and public cloud providers. Nativemulti tenancy, usage metering, and automation are included by default rather than requiring add-ons or separate platforms.

CloudStack runs some of the world’s largest public clouds and telecom environments. It is not experimental infrastructure. It is a mature, production-proven platform used by service providers managing thousands of hosts and
customers.

CloudStack enables phased migration from VMware environments. Providers can gradually move workloads, test services, and transition customers without a big bang migration or operational disruption.

Apache CloudStack supports multiple hypervisors, giving service providers and enterprises flexibility in how they design and operate their cloud environments. Supported hypervisors include KVM, VMware vSphere, XenServer/XCP-ng and Hyper-V. This multi-hypervisor approach allows organisations to align infrastructure choices with customer requirements, commercial models and technical preferences while maintaining a consistent cloud management platform.

A single Apache CloudStack deployment can consolidate multiple vSphere clusters that are traditionally deployed for separate business units or teams, bringing all infrastructure under a unified management plane. It provides a
true single pane of glass with built-in multi-tenancy, role-based access control, and secure self-service capabilities. CloudStack integrates seamlessly with CI/CD pipelines and external automation tooling through its rich and well-documented API ecosystem, enabling full infrastructure-as-code workflows.

For performance-intensive workloads, CloudStack with KVM supports GPU passthrough and vGPU configurations, making it suitable for AI/ML, VDI, and high-performance computing use cases. Additionally, Kubernetes-as-a-Service enables enterprises to deliver managed container platforms alongside traditional virtual machines within the same cloud environment.

CloudStack has an active global open-source community offering guidance via mailing lists, forums, and shared expertise. For organisations needing enterprise support, commercial vendors and service partners are available to
provide SLAs, migration support, and ongoing assistance. ShapeBlue is the leading independent CloudStack integrator globally, providing design, migration, implementation and 24/7 support services for service providers and
enterprises running production Apache CloudStack environments.

Apache CloudStack provides a unified platform to manage compute, storage, and networking resources through a single control plane. This enables providers to operate development, staging, and production environments with a consistent operational model — whether on-premises, at edge sites, or across multiple data centers.

The same APIs, templates, service offerings, networking constructs, and governance policies apply everywhere, eliminating operational drift between environments. Standardized automation and infrastructure-as-code workflows behave identically across the entire footprint, reducing operational complexity and accelerating workload promotion from dev to production.

With tightening VMware licensing and partner requirements, many providers are seeking long term independence. CloudStack offers a stable, open, and economically sustainable platform for building future cloud services.
